Outcomes of early vitrectomy with 25-gauge or 27-gauge microincision vitrectomy system for acute retinal necrosis
Purpose
To investigate the treatment outcomes of early vitrectomy with microincision vitrectomy system (MIVS) for acute retinal necrosis (ARN).
Methods
This retrospective study included 10 patients (11 eyes) who were diagnosed with ARN and underwent 25-gauge or 27-gauge vitrectomy before the onset of retinal detachment at Kobe University Hospital between April 2017 and October 2021. Patients were followed up for at least 6 months after surgery.
Results
Of the 10 eyes analyzed by vitreous fluid PCR, 6 had varicella-zoster virus and 4 had herpes simplex virus. The mean age of the 6 female and 4 male patients was 59.4 years. The progression of necrotic lesions was observed in Zone 1 in 3 eyes, Zone 2 in 6 eyes, and Zone 3 in 2 eyes. In the initial surgery, 27-gauge vitrectomy was chosen for 7 eyes (63.6%), silicon oil (SO) was injected in 10 eyes (91%), and encircling scleral buckling was combined in 7 eyes (64%). Intraoperative complications included corneal epithelial edema in 2 eyes and iatrogenic retinal breaks in 1 eye. During a mean follow-up period of 25 months, SO was successfully removed in 9 eyes, retinal detachment occurred in 3 eyes, and retinal reattachment was not achieved in 1 eye. The logMAR visual acuity 6 months after surgery was 0.00 or better (decimal visual acuity of 1.0 or higher) in 5 eyes (46%). The mean logMAR visual acuity significantly improved from 0.90±1.00 before surgery to 0.57±1.00 6 months after surgery (P=0.03).
Conclusion
Early vitrectomy with MIVS for ARN can achieve safe and favorable treatment outcomes.
